How much has your car run, 60K? If not why was a major service done? Why were the glow plugs changed, was there a specific reason? Why was the water pump changed?, if your car is under Warranty/Extended warranty - this should have been changed Free of charge including labour. Parts 1,2,3 and 12 are **not** part of the regular service and the labor charge for the remaining is ~Rs 1500. If you do not know why those parts were changed and you still paid without understanding, i don't think anyone here can help you. Edit: I just did a search on the forum and see that even the glow plugs are covered under Extended warranty. This is what happens when one does not care about the documents/Manual's that come along with the vehicle.
